As I understand we neet to find rectangle
[ 9,2] -> 11
[-4,1] -> -3 = 15
[-1,8] -> 7

Task just poorly described.

I don't think without "return" you can send any output with this method.

If we're going to engage in pedantry, the correct use would be "Hello, Name. How are you?" :)

That's not an issue, more of a "I don't like this kata's format".

Besides, there are already many such katas: https://www.codewars.com/kata/multi-line-task-plus-plus-hello-world and https://www.codewars.com/kata/multi-line-task-hello-world

I am very sorry that I don't have your smartness and great quality of explanation but I don't regret not to be a native speaker.
You will be fortunate if your clients give you clear rules...

Thank you for your time and kind feedback :)

Check the author's comment at the bottom. But a valid solution only pass with luck, so I think the tests are somewhat very prone to timeout.

Thanks! I remember doing this challenge but honestly don't remember how it works lol

Input will always be an integer greater than 0, and less than 1,000,000,000

That's already there. And I don't know if I've been clear enough, but I'll give you some examples of valid decrement sequences:

9876
765
65432

And these aren't valid given the instructions:

109
21098
32109

Let me know if your code worked when you adjust that.

Yes, that's what I meant, the instructions talk about digits, not numbers. And yes, I think a decrementing sequence can't end with 9.

For decrementing sequences, 0 should come after 1, and not before 9, as in 3210.

Otherwise it'll contradict that. A decrementing sequence not necessarily should end with 0 or 1, but there is a limit for the sequence pattern as I said. After a 0 you can't put a 9.

1 is greater than 0 but 0 is not greater than 9. Why do you say 109 is a sequence? 10 are two digits, I don't think you can use that to make it 10 and 9.

109 is not a decrementing sequence. Neither it is 2109. They don't start again from the other end.
